What spark plugs does everyone recommend, right now i have the AC Delcos platninum that the factory calls for and I figure Since i have my heads off I would go a head and put a differnt set of plugs in. If anyone has any recommendations as to what plugs i should use let me know.

 

If you are runnign basic mods (no power adders such as boost or nitrous), then the most common recomendations are the Stock AC delcos, or the NGK TR55 plugs.

Some people dont like the fact that after they changed their AC delco plugs, some of hte plat. tips were not on them, so they use the NGK plugs, which are jsut as good I have heard.

 

Definately heard about the tips coming off the AC DELCO ones. Using Autolite platinums here.

 

TR-55's i like them and i like the price 15$

 

If you want to use an AC Delco plug, but not platinum, you can use a R44LTS. More than likely cheaper than the ngk's and those ends dont unscrew either. I'd use either the ngk's or the regular ac delcos.

 

You don't need platinum. Use the autolite 106... good plug, copper, won't lose gap. I am using 104's because of the forced induct...
